Active ground cmoy: Help me learn PCB design
2 Attachment(s)
Hi all,

Based on the schematic shown here, I thought I'd have a go at creating a PCB and building a few 3 channel cmoy's.

However, this is my first try at creating a circuit board, and I may have made life a little complicated by mucking with things I don't entirely understand. Like ground planes, and miniaturisation (the board is sized so as to get 6 boards from the ExpressPCB miniboard service).

So, before I go spending money, I'd appreciated it if you could tell me:
a) if it should work at all
b) how it could be made better
c) what layout guidelines I've ignored that I really should pay attention to next time
d) if going double sided would help

Thankyou all in advance!

And here is the PDF of the copper layer, for clarity.

Well, sure nobody cared last time, but here we go again - I've substantially improved the layout, and it's getting towards something I think is nice enough to try. It contains a couple of concessions towards me making it myself, and I'd appreciate anyone with some experience there chipping in on whether it looks home-manufacturable.
